JOHN II. BUTTORFF, OF FORT COLLINS, COLORADO.

HEAD-GATE.

SPECIFICATION forming part of Letters Patent No. 726,401, dated April 28, 1903.

Application filed January 20,1903. Serial No. 189,810. (No model..

To all whom, it may concern:

Be it known that I, JoHNH. BUTTORFF, a citizen of the United States, residing at Fort Collins, in the county of Larimer and State of Colorado, have invented new and useful Improvements in Head-Gates, of which the following is a specification.

My invention relates to head-gates-t'. 6., devices for controlling the flow of Water from reservoirs, canals, ditches, and the like; and it consists in the peculiar and advantageous construction hereinafter described, and particularly pointed out in the claims appended.

In the accompanying drawings, Figure 1 is a front elevation of my improved head-gate as it appears when the gate is secured in a partially-raised position. Fig. 2 is a vertical section taken on the broken line 2 2 of Fig. 1 with the threaded rod in elevation, and Fig. dis a horizontal section taken in the plane indicated by the broken line 3 3 of Fig. 1.

Similar letters of reference designate corresponding parts in all of the views of the drawings, referring to Which- A (dotted lines in Figs. 1 to 3) is a pipe, of terra-cotta or other suitable material, having a bell a.

B is a ring, preferably of metal, arranged on the pipe back of the bell thereof.

0 is an upright frame, also preferably of metal, arranged in front of the pipe.

D D are threaded bolts extending through the frame 0 and having hooks b at their inner ends arranged in engagement with the ring B, Figs. 2 and 3, andEE are nuts mounted on the outer ends of the bolts.

In virtue of this construction it will be observed that the frame 0 may be readily connected to and as readily disconnected from the pipe A, also that the frame may be drawn very tight against the end of the pipe with a view of securing said frame in the upright position illustrated. WVhen desirable, the joint between the frame C and the pipe B may be filled with cement or other suitable material, as indicated by c, in order to render it watertight.

In practice I contemplate providing rings 13 and bolts D of various sizes in order that frames such as C may be connected to pipes of various diameters.

The frame C in the preferred embodiment of my invention comprises a base d, upright side bars 6, having gnideways f disposed at opposite sides of the end of the pipe, and a cross-heady, connected to the upper ends of the side bars and having a central aperture h, Fig. 2. One of the upright side bars 6 of the frame is provided, as indicated. by 'i in Fig. l, with graduations for a purpose presently described.

E is a vertically-movable gate arranged in the guideways of the frame-bars e and adapted when closed to rest in a seatj in the framebase d; F, a threaded rod connected to the gate and extending loosely through the aperture h in the cross-head g; G, a pointer fixed on said rod and extending laterally therefrom to a point in front of the graduations 71; H, a nut mounted on the rod above the crosshead and having, by preference, a handwheel is; I, a nut mounted on the rod below the cross-head gand having two (more or less) apertured arms Z; J, a chain connected at one end to. the frame C and having a link at its opposite end adapted to be placed over the arms Z of the nut I, and K a lock adapted to be secured in the apertures of said arms Z, Fig. 1. V

In the practical operation of my improvements when it is desired to raise the gate E the nut I is turned down on the rod F to the extent desired, after which the nut H is turned in one direction to raise the gate and rod un til said nut I brings up against the cross-head of the frame. When the gate is thus; raised, the pointer G Will serve, in conjunction with the graduations 2', to indicate the number of inches of water passing below the gate. This is an important advantage, since it enables the operator to gage the water in ditches or in the masonry over a weir in a lateral be low the gate.

To close the gate E, the nut H is turned in the direction opposite to that just mentioned until the lower end of the gate rests in the seat in the base of frame 0.

With the parts in the positions shown in Fig. 1 it will be observed that the gate may be closed by simply turning the nut H in the proper direction. Said gate, however, cannot be raised, because of the chain being locked on the arm of the nut I, which precludes turning the nut down on the rod.

When it is desired to lock the gate in its closed position, the not I is turned up against the cross-head g of the frame 0 and the chain is locked on one of the arms of said nut, while when it is desired to lock the gate in an open position the chain is passed over the crosshead 9, as shown by dotted lines in Fig. 1, precedent to being locked on one of the arms of the nut I.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood confining myself to such specific construction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.

Having described my invention, What I claim, and desire to secure by Letters Patent, is

1. In a head-gate, the combination of a frame, a gate movable therein, a threaded rod connected to the gate and extending loosely through an opening in the frame, a nut mounted on the threaded rod, between the frame and the gate, and arranged to engage the frame; said nut having an arm provided with an aperture, a chain connected to the frame, and having a link adapted to be placed on the arm of the nut, and a lock adapted to be secured in the aperture of the arm on the nut.

2. In a head-gate, the combination of a frame having side bars provided with guideways, and also having a cross-head provided with a central aperture, a gate movable in the guideways of the frame, a threaded rod fixed to the gate and extending loosely through the aperture in the cross-head, a nut mounted on the threaded rod, below the cross-head, and having an arm provided with an aperture; a chain connected to the frame, and having a link adapted to be placed on the arm of the nut, and a lock adapted to be secured in the aperture of the arm on the nut.

3. In a head-gate, the combination of a frame having side bars provided with guideways, and also having a cross-head provided with a central aperture, a gate movable in the guideways of the frame, a threaded rod fiXed to thegate and extendingloosely through the aperture in the cross-head, a nut mounted on the threaded rod, below the cross-head, and having an arm provided with an aperture; a chain connected to the frame, and.

having a link adapted to be placed on the arm of the nut, a lock adapted to be secured in the aperture of the arm on the nut, and a second nut mounted on the threaded rod, above the cross-head, and having a handwheel.

4. The combination of apipe havingabell, a ring arranged on the pipe back of the bell thereof, a head-gate comprising a frame arranged in front of the pipe, and a gate movable in the frame, threaded bolts extending through said frame, and having hooks engaging the said ring, and nuts mounted on the bolts, and arranged in front of the frame.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOHN H. BUTTORFF.
